Correct I am referring this file for list of compatible changes... Currently, I 
am looking into the old scripts manually to check for incompatible change but 
not able to catch all of them because some of compatible changes are 
dynamic/run time which are causing functionality impact... Is there a better 
way to approach this to find the incompatible changes statically before running 
those scripts..
